HAND-PUNCH.

Specification of Letters Patent.

Patented Sept. 27, 1921.

Application led February 23, 1921. Serial No. 447,123.

To all whom it may concern:

Be it knownthat I, EARL C. GREEN, a citizen of the United States,residing at Spokane, in Spokane county, and State of Whshin ton, haveinvented certain new and useful lgmprovements in Hand-Punches, of whichthe following is a, specification.

My present invention relates to improvements in hand punches of thepivoted handle, plier, type involving a pair of turret l punchescarrying a series of male dies and combined with a complementary pair ofro tary disks or anvils having female dies corresponding to the punchesof the cutting turrets.

The primary object of the invention is the provision of a device of thischaracter by means of which dates, letters, figures, and other symbolsmay be punched or perforated in sheets, preferably of paper, as for1nstance checks or receipts for prevention of fraud or for records. Thedevice is simple in construction and facile in operation, and iscomparatively inexpensive in cost of production.

The invention involves certain-novel combinations and arrangements ofoperating mechanism in connection with the plurality of turrets andsynchronously movable disks forming the male and female members of thedies, as will be hereinafter more fully set forth and claimed.

In the accompanying drawings I have illustrated one complete example ofthe physical embodiment of my invention employing two pairs ofcomplementary rotary members in which the parts are combined andarranged according to the best mode I have thus far devised for thepractical appication of the principles of my invention.

any changes could be made in the illustrated construction and Amanyapparently different embodiments of this invention could be made withoutdeparting from the scope'thereof, and it is intended that all mattercontained in the following description or shown in the accompanyingdrawingsis illustrative, and not in a limiting sense. It is also to beunderstood that the language used in the appended claims is intended tocover all of the generic and specific Vfeatures of the invention hereindescribed,

and all statements of the scope. of the invention, which, as a. matterof language might be said to fall therebetween.

Figure 1 is a side view of a hand punch embodying my invention.` F1g. 2is\an enlarged, longitudinal sectlonal view throu hthe head of thedevice, showing one punc turret and a complementary disk, therefor.

Fig. 3 is a View showing a turret and disk and a turret and disk insection, disclosin the means for receiving and disposing o the cuttingsfrom the punch.

As before stated the device is of the pivoted handle plier type, andcomprises a pair of crossed handles 1 and 2, pivoted at 3, and normallyseparated by the spring 3 suitably vembraced within the handles andnormally tending to force them apart. The operating mechanism` ismanipulated by drawing the two handles together in well known manner.

The respective handles are provided with jaws 4 and 5 and the j aw 4; isfashioned with a housing 6 for the pair of axially alined turrets 7 and8. These turrets are preferably circular disks of metal that arerevoluble on their common shaft 9 which is supported in the housing 6,and one of the turrets, as 8, is provided with an extended hub orbushing 10, projected through the housing and equlpped with an exteriornut l1 for secur- 'ing the turrets in operative position. In

Fig. 3 it will be seen that the shaft and turrets are retained, at oneend by a screw 12 threaded into the end of the shaft, and4 at the otherend by a hand wheel 13 on the shaft, outside the housing.

The two turrets 7 and 8 bear on their respective peripheries a series ofmale dies as 14, which may be numbers arranged in rotation, or letters,or other symbols as desired, and each turret is held against reverse orbackward movement on its shaft by means of a spring pawl l5, one ofwhich engages a rack disk 16 or 17 on the adjoining faces of therespective turrets 7 and 8. The spring pawls l5 are each attached at theinner face of the housing 6 as shown in Fig. 2 and prevent reverse orbackward movement of the turrets, on their shaft 9.

The complementary, rotary anvils 18 and 19 are' hollow disks,` disposedin operative relation to their respective turrets 7 and 8, and are eachprovided with a series of female dies or openings 20 in theirperipheries that register with the male dies of the respective turrets 7and 8, and are complementary and the operating mechanism thereto. Therotary anvils are supported in the bifurcated jaw 5 on the hollow axle21 in suitable bearings, and reverse orbackwardrotary movement of theanvils is prevented by means of spring pawls 22 attached at the innerfaces of the bifurcated jaw and engaging rack teeth 23 24 in theperipheries of the respective anvils.

The complementary turrets and anvils are operated or revolvedsynchronously, the turrets to rotate or revolve clock-wise and theanvils to turn anti-clockwise through the turning of the hand wheel 13,for properly adjusting the male and female [dies for unching orperforating a sheet of paper. f or adjusting these parts I provide inthe housing 6 a cross arm 25 pivoted at 26 therein, and equipped with apair of pivoted pawls 27 and 28, the former in the housing to engagerack teeth 29 on the turret 7, and the latter located between the forksof the bifurcated jaw 5 to engage teeth 30 on the anvil 18. The turret 8and anvil 19 are also provided withyrack teeth as 31 and 32 forco-action with a pair of pivotal pawls and cross arm`A (not shown) butduplicates of the members 25, 27 and 28 on the shaft or pivotal bar 26.

The pawls 27 and 28 are pivoted at 33 and 34 on the` cross arm 25, andsprings 35 hold the pawls in contact with the rack teeth of the turretand anvil, a stop 36 in the form of a pin in the housing being providedto restrain the spring pawl 27 as shown.

A main spring 37 is interposed between one wall of the housing and thecross arm 25 to hold the arm in operative position and return to normalposition after the dies of the punch have been adjusted.

Thus it will be apparent that the turrets are held in adjusted positionby their pawls 27 and detents 15 and the anvils are retained by theirpawls 28 and detents 22, after the rotary members have been initiallyadjusted with their complementary series of male and female dies inregister. Should it be desired to turn the turrets and anvils for aselected character, as for instance the symbol 0 the knurled wheel 13 isrevolved to revolve the turret 7 bringing this character to positionshown in Fig. 3. The rotation of the turret 7, through the rack teeth 29and pawl 27 causes the cross arm 25 to rock or oscillate to the right inFig. 2, and the movement of the rock arm 25 or cross arm causes the pawl28 which engages rack teeth 30, to move to the left in Fig. 2, andrevolve the anvil 18 the same distance as the movement of the turret,thus bringing the female die O into registration with the punch or maledie 0, A sheet of paper is now slipped in between the jaws of the punchand between the turret and the anvil, and the handles 1 and 2 arebrought together causing the male die to pass through the sheet of paperand into the female die, perforating or punching the paper with thesymbol 0 or other symbol that may be selected.

The above described action applies to the pair of turrets and pair ofanvils, and it will be understood that the turret 8 and Aanvil 19 may beadjusted by manipulation of the nut 11 in Fig. 3 for bringing intoregister the selected male and female dies, the action being the same asthat of the turret 7 and anvil 18.

The springs interposed between co-acting parts and between operatingparts provide for a facile manipula-tion and return action of the parts,and assist in holding the different members in normal position. Thecutting or piece of paper punched from the sheet falls within the hollowanvil, and, passing through openings as 39 in the hollow axle 21, may bedisposed of through the open end or ends of this axle as seen in Fig..3, thus preventing the accumulation of small pieces of paper orcuttings.

From the above description taken in connection with my drawings it willbe evident that a device that is facile in manipulation is provided tooperate accurately and eficiently, and in which a single set of membersor a pair of members or sets may be used as desired, and theiradjustment accomplished with convenience and despatch.

Having thus fully described my invention, what l claim as new and desireto secure by Letters Patent is 1. The combination in a punch comprisingpivoted jaws and a complementary turret and anvil rotatably supportedtherein, male and female dies on said turret and anvil, detents engagingsaid turret and anvil, and means carried by one jaw for synchronouslymoving said turret and anvil to cause registration of selected dies.

2. The combination with pivoted handles and jaws thereon, of a.rotatable turret and rotatable anvil having respectively male and femaledies thereon, rack wheels on said rotatable members and detentsco-acting therewith, a rock bar supported in one jaw, rack wheels onsaid turret and anvil, and spring pressed pawls on said bar co-actingwith said rack wheels.

3. The combination in a punch as described of a turret-die and a hollowanvil-die and pivoted jaws rotatably supporting said dies, said anvildie having a hollow supporting axle communicating with the interior ofthe die and adapted to receive cuttings from the female dies of saidanvil.

4. The combination with pivoted handles and jaws thereon one of which isformed as a housing, of a turret revolubly supported in said housing andhaving a series of male dies on its periphery, a hollow shaft supportedin the other jaw, and a hollow anvil on said shaft communicatingtherewith and provided with a complementary series of female diesopening through the periphery of said anvil, for-the purpose described.

5. The combination with pivoted handles and a jaw formed as a housing,of a turret revolubly supported in said housing and having a series ofmale dies on its periphery, a second jaw and a hollow shaft supportedtherein, a hollow anvil on said shaft having a complementary series offemale dies extending through its periphery, means Jfor detaining saiddies, and means for actuating said turret and anvil for bringingselected dies into register, as described.

In testimony whereof I aiix my signature.

EARL C. GREEN.
